I WAS SITTING AT A RED LIGHT IN THE LEFT HAND TURN LANE. A TRUCK RAN THEIR RED LIGHT HITTING ANOTHER TRUCK SENDING BOTH OF THEM CRASHING INTO MY VEHICLE. THE FIRST TRUCK STRUCK THE FRONT BUMPER AT THE HEADLIGHT & SKID ALL THE WAY DOWN THE SIDE OF THE VEHICLE THEN THE OTHER TRUCK WAS SLAMMED INTO THE SIDE OF MY VEHICLE. ALL THE DAMAGE WAS ON THE DRIVER SIDE OF THE CAR. MY CAR WAS MOVED OVER INTO THE NEXT LANE BUT NO AIR BAGS WENT OFF. THIS HAPPENED ON A HWY WHERE THE SPEED LIMIT IS 65. THE TRUCK RUNNING THE RED LIGHT WAS GOING AT LEAST THAT FAST AND NEVER HIT THEIR BRAKES. *TR

MY CAR JUST COMPLETELY SHUT DOWN OUT OF NOWHERE. IT HAS HAPPENED TWICE WHEN I WAS SLOWING FOR TRAFFIC AND WHEN I WAS IN A PARKING LOT. THE FIRST TIME I COULDN'T GET OUT OF THE CAR BECAUSE THE DOOR WOULDN'T UNLOCK. THEN THE POWER CAME ON BUT THE CAR WOULD NOT TURN OVER. IT HAS PUSH BUTTON GEAR SHIFTS AND WOULD NOT GO INTO NEUTRAL. I HAD TO CALL THE POLICE TO ASSIST UNTIL THE CAR WAS TOWED BECAUSE I WAS ON A VERY BUSY AND DANGEROUS STREET. I HONESTLY WAS SCARED SOMEONE WAS GOING TO SLAM INTO ME. THE SECOND TIME I WAS LOOKING FOR A PARKING SPOT AND IT STOPPED. LUCKILY I ALWAYS KEEP THE DOORS UNLOCKED SINCE FIRST INCIDENT HAD TO BE TOWED BOTH TIMES. AS OF TODAY IT IS STILL AT THE DEALER TRYING TO BE FIXED FOR A SECOND TIME. THEY 'THOUGHT' THEY FIXED IT THE FIRST TIME BUT IT HAPPENED AGAIN. THE DEALER HAS HAD MY CAR SINCE OCTOBER 17. THEY CLAIM THEY KNOW WHAT IT IS. THEY REPLACE SOME ENGINE MODULE AND ARE NOW WAITING ON A PUSH BUTTON FOR THE GEAR SHIFT.
